Abstract
Systems and methods for increasing the amplitude of accommodation of an eye, changing the refractive power of lens material of a natural crystalline lens of the eye, and addressing presbyopia are is provided. Generally, there are provided methods and systems for delivering a laser beam to a lens of an eye in a plurality of laser shots, which are in precise and predetermined patterns results in the weakening of the lens material.
Claims15
A system for increasing the accommodative amplitude of an eye, the system comprising:
- a. a laser for providing a laser beam;
- b. an optical path for delivery of the laser beam from the laser to a natural crystal lens of an eye;
- c. optics located along the optical path, the optics providing the capability to control the laser beam in the x, y and z directions;
- d. a control system comprising a laser beam delivery pattern, for directing the optics to deliver the laser beam in the laser beam delivery pattern to a predetermined area of the lens of the eye;
- e. the laser beam delivery pattern comprising a plurality of laser beam shots, the plurality of laser beam shots defining a first and a second area of the lens, the first area having an outer portion that essentially follows the curvature of the lens, the second area defining an excluded zone;
- f. whereby, the delivery of the laser beam in the laser beam pattern to the natural crystalline lens of the eye changes the flexibility and shape of the first area of the lens, thereby increasing the accommodative amplitude of the eye;
- and,
- g. wherein the first area has an inner diameter of 2 mm and an outer diameter of about 6 mm.
